The 300 pages of evidence shows what detectives believe led to Roopnarine's killing. The suspects apparently were after money Roopnarine received from his insurance company after a car accident.

Investigators said 17-year-old Victoria Rios told Roopnarine she would have sex with him for money. The suspects, according to the documents, had other ideas about Roopnarine's fate.

David Damus, 20, held a rifle to the victim's head and demanded cash, according to the documents. He allegedly shot Roopnarine in the face.

Konrad Schafer, 15, then "stabbed Eric several times with a kitchen knife," Rios apparently told detectives.

According to the evidence, Rios said Roopnarine's last words were "please don't kill me."

Prosecutors say the four fled with $300 in cash, a television, video game consoles, and a phone.

Investigators said the gun used in the murder was Schafer's father's gun, a .45 caliber high-point rifle that was purchased just two weeks earlier. Rios told investigators Schafer, "Keeps it loaded, always carries it with him (and) even sleeps with it."

Schafer is a suspect in 18 shootings. Two of the shootings were deadly, including Rooparine's and the random drive-by killing of a 17-year-old, David Guerrero. Guerrero was walking to a bus stop to go to work when he was gunned down.

Schafer, Damus, Rios and 20-year-old Juan Sebastian Muriel are charged with with first-degree murder. All four are being held without bond.
